CSS画三角形、圆形、椭圆形总结,第1张

CSS画正方形长方形很简单，本文就不说了。

一、三角形

1、CSS画等腰三角形

2、画直角三角形：

二、画圆形

注意：border-radius是width/height的一半（50%）。

画半圆：

半圆的画法是把高度设为宽度的一半，并且也只设置左上角和右上角的半径，且半径为宽度的一半。

画四分之一圆：是把高度和宽度设置为相等，只设置一个圆角，其半径等于高度或宽度。

三、画椭圆

斜杠前面的一组四个值分别表示四个角的水平半径；斜杠后面的一组四个值分别表示四个角的垂直半径。

四、平行四边形

margin-left是为了使得平行四边形可以全部在浏览器中显示出来

五、梯形

高度为0。有宽度没高度。

六、五边形、六边形

给你一个例子：

<head>

<title>css动画</title>

实现思路：

用一个铺满蓝色的背景的盒子，

利用：：before与after画2个圆角值不同的不规则圆形（其中一个设置透明度或者其他颜色，以便区分）：

父元素设置overflow:hidden；

最后加上animation 动画让不同规则圆形旋转起来即可:

<!DOCTYPE html>

<head>

<title>Document</title>

</head>

<body>

</body>

<style>

/* // 简单的盒子 */

.wave {

position: relative

width: 150px

height: 150px

background-color: #5291e0

/* overflow: hidden*/

}

/* // 两个不规则圆形（相对盒子进行定位，距离底部距离则为波浪高度） */

.wave::before,

.wave::after {

content: ""

position: absolute

left: 50%

bottom: 15%

width: 500%

height: 500%

border-radius: 45%

background-color: #fff

transform: translateX(-50%)

animation: rotate 15s linear infinite

}

/* // 其中一个不规则圆形调整一下样式，以便区分（或者调整animation的参数来区分） */

.wave::before {

bottom: 10%

opacity: .5

border-radius: 47%

}

/* // 旋转动画 */

@keyframes rotate {

from {

transform: translateX(-50%) rotateZ(0deg)

}

to {

transform: translateX(-50%) rotateZ(360deg)

}

</style>

</html>
